So, right around the edge of where those bolts are is the lip. If you already have the rear of the shaft and the crossmember removed which you pretty much have to do, then you just keep working around that lip until it moves freely by hand. Remember, the rubber elastomeric bearing will try to keep the lip seated. To make things worse, I think the flange it attaches to has slight ridge from being machined that help hold the lip in place. Once the lip moves by hand all the way around you just yank the shaft to the rear and it pops out. It may help to rotate the shaft and keep it at a slight angle to put tension on whatever side of the lip you are trying to dislodge at the time. Also, if you have a heat gun or hairdryer, that may help the lip side of the shaft to expand enough to help it work free. Just be careful you don't heatsoak the elastomeric bearing inside or the flange the lip attaches to or it will expand as well and get you nowhere.
